Here's the rooter
sow just grubbing around, minding her own business. The buck is browsing
the shrubs.
The whitetail
buck decides that this hog ought to be somewhere else, and lets her know
it.
She
starts moving off, and he is making sure of it. He's in velvet and
would not likely use his horns, but she doesn't know that.
In the background
is a deer feeder surrounded by a yard high fence. It allows the deer
to jump in for their specialized feed, and blocks out the hogs who will, of
course, eat anything.
It could
be that the buck is being territorial about the feeder.
